CATDOLL : CATDOLL: Silkworm breeding information and methods (What are the silkworm breeding information and methods)

1. New technologies and methods for silkworm breeding?

1. Preparation

Before raising silkworms, be sure to prepare a clean, odor-free cardboard box, and then poke some small holes on the top of the box to facilitate ventilation.

2. Incubation

Place the silkworm eggs in a carton at a temperature of 21-29°C. The incubation time is generally about 11 days.

3. Feeding

(1) When the silkworms are about to hatch, put an appropriate amount of fresh mulberry leaves into the cardboard box for the silkworms to eat.

(2) When silkworms are in the young stage, they can be fed with fresh and tender mulberry leaves. When they are in the adult stage, they can be fed with ordinary mulberry leaves.

(3) Before feeding, be sure to check the mulberry leaves carefully to pick out diseased, moldy, and insect-infested leaves, and make sure there is no water on the leaves, otherwise the silkworms will easily suffer from diarrhea after eating them.

4. Cleaning

(1) The old mulberry leaves in the cartons must be removed regularly and replaced with fresh mulberry leaves. All silkworm feces in the cartons must be cleaned up.

(2) When changing mulberry leaves to clean the feces, you must use a brush. The silkworms on the old mulberry leaves can be gently swept onto the new mulberry leaves, and then the silkworm feces and old mulberry leaves in the cardboard box are cleaned, and finally the new mulberry leaves are put into the cardboard box.

(3) If there are dead silkworms in the carton, be sure to clean it up immediately to prevent other silkworms from being infected.

2. Information about silkworm breeding?

Preparation before raising silkworms:

On the basis of planting mulberry leaves, prepare the silkworm room and silkworm tools; 7 days before raising silkworms, spray and disinfect with 1% strong chlorine, half a pound of liquid per square meter, and seal it for more than 24 hours after spraying. At the same time, the environment around the silkworm room should be sprayed and disinfected.

Quickening:

Around the eighth day after the silkworm eggs were taken out of the warehouse, you can see a small black dot at one end of the egg, which is called "green dot". If 20% of the eggs on a sheet of silkworm eggs have green dots, use a black cloth to block out the light. Starting from the day of "green dots", the black cloth should be removed at 5 o'clock in the morning on the third day, and the lights should be turned on for photosensitive incubation.

Collecting ants:

After 3-4 hours of exposure, the spring silkworms can be harvested at 9 am, and the summer and autumn silkworms can be harvested at 7-8 am. Method of harvesting ants: Cut the first unfolded leaf of mulberry tree into 0.5 cm small squares, use about 5 times the amount of leaves as ants, and sprinkle them on a dustpan lined with plastic film. Hold the silkworm seed paper in one hand and the silkworm chopsticks in the other hand, and evenly pat the back of the silkworm seed paper to make the ants fall into the dustpan, then scrape the ants with goose feathers and arrange them into a round shape.

Rearing of silkworms:

1. Temperature and humidity adjustment: 1-3 years old are called young silkworms, and they require a high temperature and high humidity environment. The suitable temperature for 1-2 years old is 26-27 degrees and the relative humidity is 90%; therefore, 1-2 years old silkworms are fully dry-reared, that is, covered with plastic film and padded with plastic film; 3 years old silkworms are semi-dry-reared, that is, only covered without plastic film, and the temperature is kept at 26-27 degrees and the relative humidity is 85%.

2. Leaves for young silkworms: For 1-year-old silkworms, use the 3rd leaf from the top bud of the mulberry tree. The leaf color is yellow with green. For one silkworm of silkworm larvae, 1 kg of leaves are used; for 2-year-old silkworms, use the 4th leaf from the top bud. The leaf color is green with yellow. For one silkworm of silkworm larvae, 3 kg of leaves are used; for 3-year-old silkworms, use the 5th to 6th leaves from the top bud. The leaf color is light green and shiny. For one silkworm of silkworm larvae, 10 to 12 kg of leaves are used. For 1st and 2nd instar silkworms, cut the mulberry leaves into small cubes 1.5 times the length of the silkworm body. For 3rd instar silkworms, cut the mulberry leaves into triangles for feeding. The amount of mulberry leaves fed each time should be appropriate, leaving a small amount of residual mulberry leaves on the silkworm seat before the next feeding.

3. Frequency and time of feeding mulberry: Feed 4 times a day, at 7 a.m., 11 a.m., 4 p.m., and 10 p.m. respectively. Young silkworms grow and develop quickly, so each feeding should be combined with expanding the seat.

4. Treatment before sleeping: (1) Desanding before sleeping: When the body color of young silkworms turns white, their bodies shorten, their bodies become tense and shiny, and part of the bodies of first-instar silkworms are covered with silkworm feces, and second- and third-instar silkworms are carrying silkworms, you can add nets to the mulberry trees to remove sand before sleeping. (2) Raising silkworms: If some silkworms have already fallen asleep and some have not, you should add nets to the mulberry trees again to lure up the silkworms that have not fallen asleep and move them to another winnowing basket to continue feeding until they fall asleep.

5. Protection during dormancy: In the early stage of dormancy, the silkworm seats should be dry. Lime powder should be sprinkled on the seats to maintain a relative humidity of 80%. When the silkworms begin to hatch, the room should be humid and the relative humidity should be maintained at 85%. If the humidity is not enough, water can be sprinkled on the ground to supplement moisture.

6. Feeding after waking up: When more than 95% of the sleeping silkworms have shed their skins, their heads have turned from grayish white to brown and have become noticeably larger. The young silkworms are crawling around looking for food. At this time, they can be fed. The mulberry leaves used as food should be slightly tender, and the amount of mulberry leaves given should be relatively small.

Silkworm breeding:

1. Rearing method: 4-5-year-old silkworms are in the adult stage, and the suitable growth temperature is 25 degrees. Silkworms have weak resistance to high temperature, humidity and carbon dioxide, eat a lot of mulberry leaves and excrete a lot. They can be raised on the ground indoors or on outdoor sheds.

2. Move the silkworms to the ground: Clean the silkworm room, disinfect it with 1% bleaching powder, and after it is dry, sprinkle a layer of lime powder on the ground. After feeding the silkworms a meal of leaves, move them to the ground for feeding.

3. Reasonable mulberry feeding: The 4th instar silkworm is the transition period from the growth of the silkworm body to the growth of the silk gland. If the silkworm is malnourished, it will affect the yield and quality. The mulberry leaves should be fresh and of good quality. Select 7-15 leaves under the top bud for feeding to achieve the purpose of good mulberry. The amount of mulberry used by the 5th instar silkworm accounts for about 85% of the total amount of mulberry. This period is the key period for reasonable use of mulberry and improving the efficiency of mulberry leaves. The feeding method of tight at both ends and loose in the middle is adopted: on the 1st to 2nd day or the 5th to 7th day of the 5th instar, the amount of leaves should be strictly controlled until the silkworms have just finished eating the mulberry leaves next time. On the 3rd to 6th day, the silkworms should be fully fed with good mulberry. Each time the silkworms are fed with leaves, the silkworms are moved and the seats are expanded to keep the silkworm heads even.

4. Keep the silkworm seats clean: During the early stage of silkworm growth, use fresh lime powder to disinfect the silkworm bodies and seats every morning. On rainy days, when the humidity is high, sprinkle lime powder twice a day to keep the silkworms ventilated and dry.

5. Collecting cocoons: After 6-7 days, the fifth-instar silkworms stop eating mulberry leaves and excrete a lot of soft green feces. Their chests are transparent, their bodies are slightly soft and waxy yellow, and their heads swing left and right. At this time, select 3-4 square clusters and overlap them horizontally. Sprinkle the mature silkworms evenly on the clusters, and hang the clusters up after the silkworms have settled. Good ventilation should be maintained during the clustering period, and the temperature in the cluster should be maintained at 24 degrees and the humidity at 85%. Generally, the cocoons can be collected and sold 6 days after the spring silkworms are clustered, and 4-5 days after the summer and autumn silkworms are clustered.

3. A beginner’s guide to silkworm farming?

1. Breeding for beginners

When a novice raises silkworms, he needs to prepare a clean, odor-free ordinary paper box or wooden box, then put the purchased silkworm eggs into the paper box, and place the box in a greenhouse that can regulate the temperature. The indoor temperature should be controlled between 21-29 degrees to promote rapid hatching of the silkworm eggs.

2. Feed mulberry leaves

Silkworms grow very fast and have a high demand for mulberry leaves. When raising silkworms, you need to prepare fresh, pesticide-free green mulberry leaves. Use a sharp knife to cut the mulberry leaves into small pieces, and then spread them on the box. Allow the silkworms to eat freely, and feed them mulberry leaves every 3-4 hours to ensure that there is enough food.

3. Suitable environment

Silkworms live in a clean environment. When raising silkworms, if the environment is too dirty, the silkworms will be infected with diseases. The boxes need to be cleaned every 2-3 days. The feces and leftover mulberry leaves in the boxes can be cleaned out, and the windows should be opened from morning to afternoon every day to ventilate the silkworms.

4. Feeding methods

When raising silkworms, the indoor temperature needs to be controlled at around 25 degrees, which is the optimal growth temperature. Silkworms of different ages like to eat different types of mulberry leaves. Silkworms aged 1-3 like to eat tenderer mulberry leaves, while silkworms aged 4-5 can be fed older mulberry leaves, which is beneficial for mulberry to absorb cellulose to spin silk and make cocoons.

4. How to raise silkworms?

Step/Method 1

Prepare a cardboard box of corresponding size according to the number of silkworms you raise, put A4 paper on the bottom of the box, and place a board on the box to prevent mice from eating the silkworms.

Step/Method 2

Put the silkworm eggs into a box, place the box in a place with suitable temperature, and sprinkle a little water in the box to increase the hatching rate.

Step/Method 3

Use scissors to cut the fresh mulberry leaves into pieces and feed them to the silkworms. Be sure to wipe the water off the selected mulberry leaves with a rag, otherwise the silkworms will get sick after eating them.

Step/Method 4

When the silkworms grow up and are about to spin silk, they will not like to eat much. At the same time, their feces will change from dark green to turquoise. You can put the silkworms that are about to spin silk in a box. Do not open the lid frequently and wait patiently for them to turn into silkworm pupae.

5. What are the correct methods and techniques for raising silkworms?

1. Mulberry leaves should be picked, transported and stored properly. Try to pick leaves in the morning or evening, transport them as soon as they are picked, and pack them loosely for fast transportation. After the picked mulberry leaves are loosened, put them in the mulberry storage pool or mulberry storage room, and store them properly to prevent them from being blown away by the wind or piled up and heated and deteriorated, which will cause waste of mulberry leaves.

2. Prevent mulberry leaves from wilting. During the young silkworm stage, use a kang bed (room) and cover the mulberry leaves with plastic film to keep the temperature and moisture, so that the mulberry leaves remain fresh. During the adult silkworm stage, close the doors and windows appropriately after feeding the silkworms, and open the doors and windows for ventilation after the silkworms have eaten about 70% of the mulberry leaves, which can effectively prevent the mulberry leaves from wilting.

3. Ensure the temperature of the silkworm room. The suitable temperature for large and small silkworms is 24℃ and 25℃ respectively. Within the suitable temperature range, the silkworms have a strong appetite, which reduces the defective mulberry leaves and improves the leaf-silk conversion rate.

4. Promote less-return rearing and mulberry-strip rearing. Labor-saving silkworm rearing technologies such as flat three-dimensional rearing of small silkworms once a day, rearing of full-age silkworms twice, and rearing of large silkworms in mulberry strips not only improve the efficiency of silkworm rearing, but also help silkworms eat mulberry leaves, saving about 5% of mulberry leaves compared with ordinary rearing.

Additional information:

Summer and autumn silkworm breeding should pay attention to

1. Prevent pesticide poisoning. During the silkworm-raising season, do not spray organic pesticides such as dimethoate in the silkworm room and the fields near the mulberry fields, as the smell will cause poisoning to the silkworms; mulberry leaves should be fed to the silkworms only after they have been tested and confirmed to be non-toxic.

2. Mosquito-repellent incense or mosquito repellent or insecticide is prohibited in the silkworm room. If it is used in the house near the silkworm room, the doors and windows of the silkworm room should be closed to prevent the silkworms from being poisoned.

3. Screen doors and windows should be installed in the silkworm room to prevent flies from entering the room and harming the silkworms, and "silkworm fly killing" emulsion should be added or sprayed on the silkworm bodies to kill the maggots.

6. How to learn the complete set of techniques for raising silkworms?

1. To raise silkworms, you must first buy silkworm seeds, which are silkworm eggs. This product has the ability to hatch silkworms. Every spring, when the temperature remains around 20 degrees, silkworms will hatch from silkworms.

2. After the silkworms hatch, you need to pick mulberry leaves to feed them. The chewing ability of silkworms is not that strong, so you should choose relatively tender mulberry leaves. There should be no water or pesticides on the mulberry leaves.

3. Silkworms can be raised in paper boxes. If the scale is larger, they can be raised in special bamboo boxes, which must be breathable, hygienic and clean.

4. Raising silkworms has relatively high requirements for the environment. There must be no fumes, no mosquitoes, no mosquito coils, no spraying of pesticides, and no dust. Otherwise, the survival rate of silkworms will be affected.

5. The process of raising silkworms is very hard. Silkworms need to eat mulberry leaves day and night, and as they grow older, the amount of mulberry leaves they eat increases.

6. Silkworms usually spin cocoons in about a month. Before spinning cocoons, we need to build a frame and let them go up the mountain. It will take about two or three days for the silkworms to spin a snow-white cocoon.

7. How to raise silkworms?

1. Steps of silkworm rearing

(1) From silkworm ants to silkworm babies

Suitable temperature: 20-25℃.

Time: 2-3 days to hatch.

Collecting ants: The young silkworms will crawl out of the egg shell like ants. Use very light gestures to collect them and lead them to the tender leaves. Note: The silkworm eggs need to be kept in a ventilated and dark place during the incubation period.

(2) Feeding silkworms

The living habits of silkworms are: sleep when full, eat when awake;

Living environment: Plastic or wooden flat box,

Note: The mulberry leaves should be fresh. You can also collect them in a plastic bag each time, use a few leaves every day, and sprinkle some water on the rest and put them in the refrigerator to keep them fresh. The collected leaves will have some dust, so you can wash them and dry them. You must dry them, otherwise the young or adult silkworms will have diarrhea if they eat them.

(3) Silkworms spin silk and make cocoons

Molting: After molting once, the larvae become the second-instar larvae. Each time the larvae molts, they become one year older. They molt a total of four times.

Cocooning: 7-8 days after molting four times, the owl stops eating mulberry leaves, its body starts to shine, and it begins to look for a suitable place to start cocooning.

Note: Put some supporting objects in the silkworm box to help the silkworms make cocoons.

(4) About silkworm droppings

Silkworm feces, also known as silkworm sand, has the effects of curing dampness, itching, removing internal heat, removing rheumatism, and improving hearing and eyesight. Many elderly people dry it and make it into pillows for their newborn babies to sleep on. Silkworm feces, black particles, can be used as medicine in traditional Chinese medicine and are also good nutrients for plants.

(5) Silkworms break out of their cocoons

The silkworm sheds its skin for the final time (fifth time) in the cocoon and becomes a pupa. After about 7-10 days, the pupa turns into a silkworm moth and emerges from the cocoon.

Note: The fat one is the mother of the silkworm, and the thin one is the father of the silkworm. Let the father and mother of the silkworm live together, and you can see a lot of silkworm eggs the next day. If you protect them well, these silkworm eggs can hatch again in the spring of the next year.
